This law is ALWAYS valid. Though the only way it is really obvious is in chemical reactions. When two chemicals react, some people used to think that it was destroying the materials (IE fire), though if you were to gather EVERYTHING from the reaction (in the case of fire, the gas, the ash, etc...) it would have EXACTLY the same mass as before.

In what situations would mass be conserved?
This is a general law of nature - the law of mass conservation.
What law represents a balanced chemical equation?
The law of conservation of mass, which states that in a closed system, mass is neither created nor destroyed, it can only change form. This means that in a chemical reaction that takes place in a closed system, the mass of the reactants equals the mass of the products.
Which law physical science must be followed when balancing chemical equations?
the law of conservation of mass
What law states that the mass can not be lost or gained in a chemical reaction?
The law of conservation of mass states that in a chemical reaction the mass of the reactants must equal the mass of the product.
What is the law that states that a chemical compound always contains the same elements in exactly the same proportions by w eight and mass?
Law of definite proportion, sometimes also called the law of constant composition.
In what situations would mass be conserved?
This is a general law of nature - the law of mass conservation.
Is a rusted pipe which mass has increased violate the law of conservation of mass?
No, it is not true; the law remain valid.
When water evaporates why does the mass stay the same?
The law of mass conservation is generally valid.
What law states that mass cannot be created or destroyed in chemical or physical changes?
The law of conservation of mass/matter states that mass/matter cannot be created or destroyed in chemical or physical changes.
What law represents a balanced chemical equation?
The law of conservation of mass, which states that in a closed system, mass is neither created nor destroyed, it can only change form. This means that in a chemical reaction that takes place in a closed system, the mass of the reactants equals the mass of the products.
What scientific law is satisfied when balancing equations?
Law of Conservation of mass(atomic mass). As mass can be considered relative to energy, therefore Law of Conservation is also correct but Law of conservation of mass is is much more accurate because here mass is a much more accurate term that is required here. Here, since, we are balancing molecules, then we require atomic or molecular mass.
When water evaporates does it make more water than it started off as?
The law of mass conservation remain valid.
What are the law of conservation of mass as it relates to phase changes?
it is the same as the law of conservation of mass
How are the law of conservation of enegry and the law of mass similar?
The Law of conservation of Energy applies to mass as mass is a form of energy, E=mc2.
Which scientific law predicts that the mass of the reactants before a chemical reaction will equal the mass of the products after the reaction has taken place?
Law of Conservation of Mass (aka Law of Conservation of Matter)
Is law of conservation of mass valid during earthquakes?
Oh yes, mass is conserved during earthquakes. No mass is created or destroyed, it just gets violently re-arranged.
Which law physical science must be followed when balancing chemical equations?
the law of conservation of mass
